Question

a rectangular field is such that its length is one and a half times its breadth. A thick white line drawn all along the edges of the field in the total length is white line is 200 m find the length of the field​

Answer 1

Given that peremeter is 200m
We take 5he breadth as x
So, the length will be 1.5x
Now,
Peremeter= 2(l+b)
➡️ 200= 2( x + 1.5x )
➡️ 100= 2.5x
➡️ 100 x 10/ 25= x
➡️ 40= x
So, breath is 40m and length is 60m

Answer 2

let

breadth=x

length=1.5x

perimeter =2×l+b

200=2×x+1.5x

200=2×2.5x

2.5x=100

2.5×10/100×10=x

25/1000=x

x=40

breadth=40

length=1.5×40

=60
